Kernel .config of a 32-bit system where the receiver works

Tested kernel versions: 2.6.39.3, 3.0.1, 3.0.2
Tested firmware versions: 4.95, 5.1

The receiver works (almost) fine on 32-bit systems, except some weird keymap
rambling:

The last three lines above are repeated *forever*, every 500 milliseconds, with
varying numbers after the first message (8/19 and 8/0 appear as well).

The most importantly, modprobe -r dvb_usb_af9015 causes a kernel *freeze* (no
panic, no log messages), no matter if the receiver is connected or not. (The
machine is unreachable via network after that.)

Due to a total lack of documentation, I have no idea what the keymap error
mesages mean and how to fix these issues. (I also don't know whether the remote
controls actually work. They used to work in the past, but I don't have them
handy now.)

The module is modprobe'd with 'remote=2'.

There are two attachments:
    * kernel .config from the 32-bit machine where the receiver works
    * kernel .config from the 64-bit machine where the receiver fails and the
module freezes the kernel when unloaded
